title: [Validation of an acute bronchiolitis severity scale].
abstract: BACKGROUND
  Acute bronchiolitis (AB) is a very common disease, with a high rate of seasonal hospitalization. Its management requires homogeneous clinical interpretations for which there are different approaches depending on the scales, none of which are properly validated today.
  
  
  OBJECTIVE
  To create an AB severity scale (ABSS) and to validate it.
  
  
  METHODS
  The development of a parameterized construct with a gradual cumulative score of respiratory rate, heart rate, respiratory effort, auscultation of wheezing and crackles, and the inspiration/expiration ratio. Also, the validation of the ABSS performed on patients diagnosed with AB, the reliability measured by observing the behavior of internal consistency, test-retest, external validity and inter-observer agreement.
  
  
  RESULTS
  From a total of 290 measurements a Cronbach's reliability alpha of 0.83 was obtained; Kappa agreement index of 0.93 in the test-retest agreement, and Kappa index of 0.682 (α<0.05) for inter-observer agreement.
  
  
  CONCLUSIONS
  The ABSS can be a reliable tool for measuring the severity of AB.
